ANALOG INPUTS (P3 AND P11)

Voltage and current signals are connected at the screw terminal, at
P3 and P11, respectively. All analog input signals are filtered
using the on-board antialias filters before being presented to the
analog inputs of the energy metering IC.

CURRENT SENSE INPUTS (P11)

P11 is a three-way connection block that allows the ADE71xx/
ADE75xx/ADE51xx/ADE55xx to be connected to a current
transducer.
The RC networks are the antialias filters that are required by the
on-chip ADCs. The default corner frequency for these low-pass
filters (LPFs) is selected as 4.8 kHz with a resistor of 1 kΩ and a
capacitor of 33 nF).
